FEEDING AND ROLL-WINDING APPARATUS.

Application filed August 1, 1927. Serial No. 209,849.

The invention primarily has for its object to provide certain new and useful improvements in apparatus for feeding and winding cotton batting in rolls without subjecting it to any appreciable pull or stretching tendency so that the efficiency of the batting as an upholstering medium will in nowise be impaired.

As the continuous length of batting is fed from the final pressing and feeding rolls of the forming machine, it is commonly rolled into a roll of suitable size for convenient use. Due to slippage and the rate of speed at which the winding rolls are driven because thereof, the peripheral speed of the roll being formed constantly varies relatively to the constant linear speed at which the batting is being fed, the said peripheral speed being much greater than the said linear speed at or near the completion of the rolling action, causing a pull on the batting which either greatly-strains the fibres thereof or breaks the continuous length of batting being rolled. Some efiorts have been directed to the solution of this problem and complicated change speed transmission gearing has been devised to gradually alter the speed of rotation of the winding roll mandrel in an effort properly to balance the "feeding'and winding speeds. Such mechanisms hav solved the problem but partially, and due to their cost of production and use and the impracticability and difiiculty of making adjustments of the mechanism constantly to accord with the'adjusted speeds of the forming and feeding mechanisms, I do not find them practical for theuses herein explained.

Therefore, in its more detailed nature, the invention seeks to provide a simple, inexpensive and efficiently operable apparatus to wind the batting in a roll, including a slack loop forming meansto form a slack loop during the first stage of the winding operation and to dissipate that loop during the final stages of the said winding operation, said apparatus being'so' timed in cooperative relation that the whole of the slack loop will be dissipated just at the completion of the roll forming action and without imparting any stretch or pulling action to the batting. This apparatus eliminates all complicated and expensive variable change speed gear mechanisms.

With the above and other objects in view that will hereinafter appear, the invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, then be particularly pointed out in the appended claims, reference being had. to the accompanying drawing, in which Figure l is a somewhat diagrammatic side elevation illustrating the invention.

Figure 2 is a plan view of the parts shown in Figure 1.

In the forming of cotton batting in continuous lengths, and the winding of such batting into rolls for shipment and con-' venient use,care must be exercised to avoid subjecting the batting to any appreciable tension or distending pull so that the fibres will not be distended or strained and the resilient upholstering qualities of the batting impaired. In the machines for forming such batting th batting is passed through feeding and pressing rolls so cooperatively arranged and timed that they do not subject the batting to strain and press the same just enough to interlock the fibres of the layers or foldswithout compacting or matting the same. In my Patent No. 1,589,667 issued June 22, 1926, a bat forming machine of the general typ mentioned is disclosed and in my Patent N 0. 1,558,059 issued October 20, 1925 a winding unit such as is re ferred to above is disclosed.

This application is directed to a combination of the delivery rolls of the forming machine and the winding devices of the winding unit and means between the machine and unit to form a compensating loop which will compensate for differences of speed of travel of the batting during the winding operation in a manner assuring against subjecting the batting to pull or tension and without the employment of complicated and expensive change speed gearing.

In the drawing, in which like numerals of reference indicat like partsin all the figures, 1 generally designates the framing of any suitable type of bat forming machine and 2 the delivery feed and presser rolls which are shown as mounted in the usual bearing standards 3. The rolls 2 are rotated at the desired speed thro h the of the power chain or belt 4 ron; any suitable source of power on or near the machine.

B a s a da ds 5 a moun ed pon h deliv ry end of the m c in frami g i parallel spaced relation and serve to supp a P of idler rollers P o e n transversely of the forming machine delivery end and in spaced parallel relation. The pur ose of these idler rollers will be explained later. i i

The windingstand or unit, whichmay also 'beof any approved type such as that refenred to above, is generally indicated at 7. The unit includes vertically slotted end plates on wings 8, the slots. of which are adapted .to-receive the. winding mandrel 9 adapted to be rolled by and positioned above and between the pair of power .and support rollers 10.

Power is imparted to. one of the. rollers by the transmission. chain 11 which also T takes over a sprocket on the shaft of one of the rolls2sothat therollens 10 and the rolls 2 will always rotate at constant ,-l-.e lativ,e speeds regardlessof theadjnstment of speed of the forming .machine mechanisms. The other nollen 10 isrotated through the trans: mission connections 12 at like speed with its companionroller 1 0.

winding unit may be equipped with any suitable traversing guide 13, and as such a guide described in detail in the patent .above'referred to, further detailed description thereof is deemed unnecessary.

In operation, as the continuous length of batting 14 leaves the delivery feed and resser rolls 2 it passes overthe idler r011 era. 6, through the guide 13 and around the mandrel 9 'upon which the roll is being wound. The roll being wound rests 111.011 the rollers 10. and is rotated by the said rollers, it being understood that these rollers rotate at a" constant speed relative to the s ed of rotation of the rolls 2. During the rst portion of rolling operation, the roll being relatively small,' the. peripheral speed of the roll or the Winding speedof the batting is muoh less than the linear speed or travel. speed of the batting through the rolls 2' and consequently a compensating loop 115 will form between the idl r rollers 6, 'loop gradnallyincneasilig in length until the maximum length is reached'at the moment when the winding speed of hflbfl ting or the peripheral speed of the roll being formed. ppro imate the travel sp ed of the batting through the feed rolls 2. From this time on the peripheral Speed of the roll being formed will be in excess oi the linear speed of the batting or trayel speeduthmugh th rol 2 in adu l y 1B? creasing ratios and the compensating 100p will be gradually dissipated until the roll is completed or wound to its predetermined d' meter when 139 loop will haye been com p on y d s g t e the bat es all P flatly over t e rollers 6.
